Notes:

1. When measuring output ripple, it is recommended that an external

0.47 μF ceramic capacitor be placed from the +Vout pin to the

-Vout pin for single output units and from each output to common

for dual output units. For noise sensitive applications, the use of

3.3 μF capacitors will reduce the output ripple.

2. Transient recovery is measured to within a 1% error band for a

load step change of 75% to 100%.

3. Operation at no-load will not damage these units. However, they

may not meet all specifications.

4. Dual output units may be connected to provide a 10 VDC, 24 VDC,

or 30 VDC output. To do this, connect the load across the positive

(+Vout) and negative (-Vout) outputs and float the output com-

mon.

5. The converter should be connected to a low ac-impedance source.

An input source with a highly inductive impedance may affect

the stability of the converter. In applications where the converter

output loading is high and input power is supplied over long lines,

it may be necessary to use a capacitor on the input to insure start-

up.

In this case, it is recommended that a low ESR (ESR <1.0Ω at 100

kHz) capacitor be mounted close to the converter. For all models,

it is recommended a 1.5 μF be used.

6. The optional remote

on/off control pin

is referenced to

the

-Vin pin.

The standby input

current is typically

0.1 mA (0.2 ma

maximum).

7. It is recommended that a fuse be used on the input of a power sup-

ply for protection. See the table above for the correct rating.
